Dodge Durango Idle Reving Problem

REPLACED THE THROTTLE POSITION SENSOR AND IT FIXED THIS PROBLEM!

My 2002 dodge durango v8 4.7L revs up and down at random when idling. It could be sitting there in park idling fine and then all of the suden rev up to about 2000 rpm's without me touching the gas. It does this while stoped at red lights and stop signs aswell. I have to hit the brake quick to avoid hitting the car in front of me. I took it to the place where I bought it to try to get it fixed and they just told me it didnt do it for them so they couldnt fix it. Well I did some research on my own and found out that it might be the THROTTLE POSITION SENSOR. So I am going to try getting one and put it in and see if it fixes the problem. I hope so because it's really annoying!

Had this exact problem on my 2001 Dakota (4.7L v8) but it ONLY seemed to happen on interstate/highway driving. Several mechanics said it was the transmission or the rear differential but I had read where the TPS could cause those symptoms as well. Had them replace the TPS and it's been fine ever since. This was about a year ago now.

@Techie1935 Yeah I thought it was my transmission at first too because the reving would sometimes cause the transmission to shift when it shouldnt.

Thanks! wish I saw this a while back..spent about $1000.00 over the last two years having a mechanic try to straighten this out. Correction ex-mechanic, I can tell he never changed the TPS just by looking at it. I love my 2003 durango, it's got 190,000mi and now is running like the day I bought it :-)

@gl797 Yeah I had mine at the garage a couple times and the mechanics couldnt figure it out. I finally did some research online, fixed it myself and posted this here to help others with the same problem. I love my durango too! Mine only has 80,000 on it so far and it drives really nice! I dont plan on ever getting rid of it!

Could be the ignition.

[rockey90]

@XGNRambo It was the Throttle Position Sensor. I replaced it and it idles fine now.

[Techie1935]

@Techie1935 Should note that they said it was the transmission because it almost always came with a downshift while on the interstate/highway but not always. Most of the time the variance in the RPM would cause the transmission to shift thinking I had stepped on the gas so it would give me more power. (NOT good when the roads were icy!)

@gl797 sorry forgot..on the 4.7L I didn't need to remove anything to get at the sensor.

my dodge neon did that but it eventually stalled out..
